i'm still unable to solve this problem. The shipping for a LP Bin and a Bin-e is $70.60, together in the same cart. If you order them Separately it's only $63.10. Zipcode used is 08831
i just tested it with 2 products that are the same weight. Added both to the cart and no problem. The shipping is the same if i buy both together or separately. Now, I changed one weight to 850 Ounces and kept the other at 200 Ounces. Then, i get the overage of $7.50, more than if you buy separately.
